Be it, known that llnwixiii) Kenn:- sciuiiirr. a citizen ot' the United States, residing at Long` island City. in the county ol Queens and tftate ot New York, has iuvented certain new and useiul Improvements in Selective Mechanisiii. ot which the following` is a specitication.

rThis invention i'elate-s to selective mecha-- uisins o'if the character in which :i j iluralitjP et mechanical operations are selectively controlled from a remote point. such as motor control; switchingl operations and the like. lt is particularljv useful iii printing telelgraph machines, and the preferred embodiment herein disclosed is shown and described in its relation to a printing tele graph machine, such as shown in copendinp application Serial Number .330.880, tiled January 21. 1922.

The present invention involves improve ments in the type ot' selector disclosed in the above mentioned application. and has for its object` the production ot a simplified and more etlicient mechanical structure. A fui'ther object is the production ot a selector in which a complete overlap is obtainable. without the use ot storing); trames or carriers previously in common use. and without the necessit \v ot resorting to intermediate members used bv other well known types oit mechanisms. B v overlap7 is to be understood the operation ot a mechanism in which a s icceeding selective combination is received while the precedingi selective mierations are beine' completed. This resuits in a considerable increase in the spe-ed oi operation.

Thesey and such other objects ol' the iuventiou as will liei'eiiiatter appear. are attairefl in the preferred embodiment herein described. and shown in the accoiiijmnj'ing` di l:ings in which:

As is well understood in the art, iiicomingr selective combinations o'l electrical impulses are distributed in proper sequence te selector magnets 1 to 5. Individual to each selector magnet is an armature 6 (Fig. 2). ,"irmatiires (l are pivotally mounted at (F '7) in slots 8 on supports 9, and are limited in movement by adjustable stop members 1l. Springs 10 normally hold armatures (S against stops 11. Mounted on armatures (l are extensions 12. Extensions 12, at their ends are engaged by adjustingiiieaibers 1S. hleinbers 13 are pivotally mounted at 14 (Fig. 1) on supporting member Set screws 16 (Fig. 1) engage slots in members 13. In assembling" the selector mechanism. members 13 are adjusted about pivotal points 14 until armature extensions 12 are in proper relation with respect to selector bars 17 to 21 inclusive (Fig. 2). and screws li are then tightened to clamp meinbers 13 in place. Due to the pivotal mounting o'l armatures G in slots S, and a slight side movement permitted b v the looseness oiI mounting` on support E), adjustment ot the extension members in the diiectioii ot the lengt-h o'li the selector bars may thus be made.

A series ot' live slots 22 (Fig: 1) are cul'y into the lower edge ot bars 17 to 2l. The slots in bar 1T are placed iu such a manner. that with magnet 1 de-energir/,ed and arina ture 6 thereot' in retracted position. the shoulder formed by the first slot to the right in Fig. 1 engages armature extension 12 ot magnet 1 to hold bar 17 to the lett in unselected position. The remaining four slots are positioned in such a. manner that bar 17 clears the extensions 12 of magnets 2 to 5 on movement ot' 1T in either direction. The slots on the remaining bars are positioned in.

similar manner, so that armature extension 12 of magnet 2 acts as a stop to hold bar 18 in unselected position, and magnets 3, 4 and 5 control bars 19, 2O and 21 respectively. It will be apparent that each extension 12 acts as a stop to retain a single selector bar against motion while permitting free motion in both directions of the bars not controlled thereby. Selector magnets 1 to 5 control bars 17 to 21 respectively. Springs 23 are carried by a bevelled block 24 supported adjustably by screws 25 and 26. The tension of springs 23 may be simultaneously adjusted by adjusting screws 25 and 26.

Extensions 27 (Figs. 1 and 7) of arma-` tures G extend rearwardly and downwardly and are engaged by latch members 28. Latch members 28 are pivotally mounted on spindle 8O (Figs. 7 and 8) extending across the mechanism` rigidly supported in lugs 81 and 82 (Figs. land 8), and held in properly spaced relationby slots''in guide plate 84 (Fig. 1). Springs 85, fastened to supports 9 by clips 86 and pins 87, hold latches 28 in engagement with extensions 27. Fins extend through openings in extensions 27 and springs 10` are fastened thereto. As armatures 6 are attracted by magnets 1 to 5, extensions 27 slide over shoulders 88 `of latches 28 (Fig.` `7) and latches 28, moving under the influence of springs 35, lock the actuated armatures 6 in attracted position.

As any one of the latches 28 moves upwardly on energization of the respective selector magnet it actuates bail 89 (Figures 1, 2 and 7). Bailv 39 extends across all of the latches 28, and at its ends is bent at right angles forming `arms 49 and 41 which are rigidly fastened to collars 42 and 48. Collars-42 and are fastened to spin-` dle 44 (Fig. 8) rotatably mounted in supports 81 and 32, and as 89 is raised by latches 28, 44 is rotated. Rigidly fastened to 44 is a rocking `member 45 (Figures 8 and and loosely mounted 011.44 is locling member 4G. Integral with 46 is a projection 47. To collar 48 (Fig. 8) rigidly 'fastened to44, is fastened a helical spring 49. Spring49 forces member 46 forward to hold lug 47 in contact with rocking meniber 45. Toe 59 of rocking member 45 is adapted to be engaged by the teeth of ratchet wheel 51l igures (S and `latchet Wheel 51 is rotatably mounted on spindle 52, carried by support 82, and as it rotates member 45 is rocked and actuales bail 39. VVithlarmatures Glin normally retracted'position, bail 39 rests on latches 28, locking member, (Slis thrown for 1ard, and toe 50 is disengaged from ratchet wheel 51.

After'inagnets 1 to 5 have been controlled in accordance with an incoming selective `combination of signals, a local impulse is sont. bythe usual distributor. to operating magnet 58. Armature 54 of magnet 53 is pivotally mounted on support and held in normally retracted position against stop 56 by spring 57. Locking member 46 is normally positioned beneath a bloclr` 59 carried by an extension 58 of armature 54, and prevents actuation thereof until one of the armatures 6 has been actuated. Wfhen an armature G is actuated, the corresponding latch 28 raises bail 89 and rocks 44, thereby moving 4G out from under block 59 to permit movement of armatme 54 when a local impulse is received by 58. Extension 58 carries aprojection 60 (Figure and a screw 61 locked in place by a locl nut.

Fivotally mounted on support 63, at points 64 is a selector bar locking member G5. Member 68 is bent upwardly to form an extension 67 (Fig.` 4) adapted to engage shoulders (58 and 89 on the lower surface of selector bars 17 to 21. rin eX- tension 70 of member 66 is fastened to spring 71, the lower end of which is attached to a pin 72 `projecting from support 68. (Figures 1 and Under the influence of spring `7.1, member 8G is pressed upwardly against the selector bars and engages shoulders `6801"(39, depending on the position of the respective selector bars.

Restoringmember 75 is pivotally mounted at its lower 'end in support-58 at 75. Restoring pawl 77 is pivotally mounted at 78 on the upper end of members 75. Projecting from pawl 77 is a stop member' 79 carrying a pin 89. A. spring 81, fastened to pin 8() at its yupper end and to a pin 82 at its lower end noil'mally maintains pawl 77 in raised position engaging selector bars 17 to 21 with stop 79 against member 7 5. lt willl be apparent `that stop 79 in this manner limits upward motion of pawl 77 under influence of spring 81. Screw 61 extends through an openingr in pawl 77 and acts as a stop to limit. `the pivotal movementof member 7 away from the selector bars. Extending from member 75- is an operating pin 88. Operatingpin 88 is engaged by an extern sion 84 of a printing frame l5, of a printingtelegraph machine, such as is disclosed in thc copending application, Serial Ninnber 580,889, above mentioned. stirring 85 resiliently connects extension 84 ufitl. re storing member: 75. As disclosed in the copending application, printing frame 85 in pivotally mounted at 86 and on a forward stroke thereof a selected pull bar 87 drops into aligned slots of the selector bara and is actuated to print a selected character.

rlhe operation of the printing frame is controlled by closure of contacts 88 and 89. Contact 89 is mounted on a spring member 99, normally tending to separate 89 from 88. iinarm 91 (Fig. 8) `pivotally mounted at controls spring member 90. 14n open lll) i ating member 95 for arm 91 .is pivotally connected to ears 93 on arm 91 at 94. Member 95 extends vertically, and extension 96 thereot pases through a guide hole in block 59 and armature extension As armature 54 nears the end ot au energizing stroke, block 59 engages shoulders 97 ot member 95 and presses 95 downwardly. Actuation of 95 moves arm 91 to close contacts S8 and S9. A latch arm 98 pivotally mounted at 99 to a block 199 is normally held against the end ot' arm 91 by a spring 101. As contacts SS and 99 closed, the end et 91 moves downward until recess 192 permits spring 191 to move la ch 9S inwardly thereby locking contacts SS and 89 in closed position, as shown S printing it'rame S5 nears the in Fig. o. end ot its stroke, an extension 193, carried thereby engages the upper end of arm 9S and releases arm 91, thereby permitting contacts 88 and 89 to restore to normally open position.

Pivot-ally mounted on block 59, carried by armature extension 5S, is an actuating pawl men'iber. A spring 195 normally holds pawl tooth 199 in engagement with ratchet Wheel 51. As armature is depressed, tooth 196 rides over the following tooth ot ratchet wheel 51, and as armature 51 retracts under intluence of spring 57, when magnet deenergizes, ratchet wheel 51 is stepped and rocks member -'..5. Movenient oit actuates bail to release armatures G, and condition selector magnets 1 to 5 tei receive a succeedingl selection.

Operation.

1n event none ot the magnets 1 to 5 inclusive are energized by incoming` impulses, member 19 remains positioned under block 59, and although a local impulse is sont to operating magnet 53, actuation ot' armature 5t is prevented. However` ij any ot the magnets 1 to 5 are energized,` the respective armatures ti are attracted, and members 27 are moved to permit actuation ot the corresponding latch members 2S. Upward uovement ot any one oi: the members Q8 ac.- tuates hail 39 to roch member 4.5 on spindle il and holds 99 in upward position. Movement ot' 45 removes the end ot #t9 trom under block 59 to permit actuation ot' armature t9 is held in removed or actuated position until latches are restored. Upward movement ot' latches lo also causes extensions 27 'to slide over shoulders Btl and locks armatures (i in attracted position. Assuming that magnets l, il and 5 are actuated by an incoming combination ot electrical impulses, their armatures G will be locked in attracted position. Extensions 12 ot' these magnets u ill tliercitore be withdrawn trom slots ot selector bars 17. 1.9 and 21.

locking member GG holds selector bars 17 to 21 in unselected position. After the armatures oi magnets 1, 3 and 5 have been set, a local impulse is sent to operating magnet 53. Since locking member 4G has been ac tuated, armature 511 is attracted. Movement ot' armature first causes projection GO to disengage pawl 77 from selector bars 17 to Q1, and then causes screw (i1 to disengao'e locking member G9 from shoulders 68. As member G9 is depressed, selector bars 17, 19 and 21 are moved to the right in Fig. 1 under the influence ot springs 23. Since magnets 2 and et, have not been energized, extensions 1Q o't' their arniatures remain in slots 22 and engage thc shoulders formed thereby in bars 1S and 2.9. liars 18 and 29 are therefore held against movement. Movement of bars 17, 19 and 2l. aligns a` series otl lslots in well known manner to permit selection ot an aetuating bar 87.

After movement ot bars 17, 19 and 21 has been pern'iitted, further movement o't' armature 5-'t causes block 59 to engage shoulders 97 on bar 95 and rocks arm 91 to close contacts SS and S9. As contacts 8S and S9 are closed, latch member 9S locks them in closed position. Closure ot contacts S8 and 89 causes printing trame 85 to move toi-ward. ltoiwvard movement ot S5 permits a bar 87 to drop in the aligned slots, and then moves bar 87 'forward in the aligned slots to print a character. Forward movement ot iframe 85 causes Sil to stress spring S5 and thereby move restoring member to the left in Fig. et. As panv 75 was depressed and G9 released, bars 17, 1,9 and 21 moved to the lcit`t in lEig. si, and over pawl 77. As movement o'f 75 under the influence of spring S5 continues, pawl 77 is disengaged from the selector bars and moved upward under in- 'tlueace of spring S1 in a position to re--eng-.ige the ends of the selector bars tor restoration on the restoring .stroke o* 95. Movement ot 75 is limited by engagement o'tI pawl 77 with screw 61.

The local impulse sent to magnet 53 is momentary, but ot sullicient duration to actuate. armature 51 completely. lVliile trame S5 is being actuated to print a character, armature 5l restores under the influence ot spring 57, permittingY member titi to loch' bars 17 to 2l, in their selective positions. Further upward movement ot' 5-lcauses pawl member 191- to actuate ratchet wheel 52, causing bail 239 lo depress latches 2S which have been raised and thereby release armatures (i ot magnets 1, 3 and 5. These armatures restore partially, until members 12 engage the lower edges ot' bars 17, 19 and Q1 which have been locked in actuated position. Sui. ticient movement otl the armatures is per Normally, mitted to free members 27 from engagement with shoulders 38, thereby immediately placing all the selector magnets incondition tor a succeeding selection. Assuming that on the neXt selectiommagnets 1 and l are energized, their armatures 6 Will be locked in attracted position, and bail 39 ivill again be raised by latches 28.,

As frame approaches the end ot the printing' stroke, member 103 engages latch member Q8, and releases contacts 538 and 89. Opening; o'l' contacts 88 and 89 cause printing iframe S5 to restore under the action of its spring. Restoration oft frame 85 first raises bars 87 from engagement With the selector bars', and then member 84e in engagement with pin 83 forces member 75 to the right in Fig'. l-r. causing' paivl 77 to engage the actuated bars 17, 19 and 21, and moves these bars to unselected position. Armatures 6 et ma'grnets 1 and fl have been locked in actuated position by energization of these magnets. Armatures t3 of magnets 3 and 5, however, are now 'tree to and do restore completelyT by moving; into slots 22 on the resto 'ation 'of bars 19 and 21. Bars 19 and 21 will therefore be held against movement until armatures 3 and 5 are again energized in a selection;

As soon as the printingiV trame has completely restored, and has restored the actuated. onesotl bars 17 to 21, another local im-` pulse may be sent to magnet 53. Bars 17 an'd 2O Will move under the iniiuence of springs 23 and bars 18, 19 and 21 will be held against movement. Printing* and the overlap selection'oit the succeeding' character Will proceed in the above 'described manner.

It will be apparent that a simplified selecting mechanism has been described, in which a complete overlap Within the selector is secured, Without the interposition ot storage or intermediate members between the selector magnet armatures, and the selector bars. It Will also be apparent that the succeeding character may be set up on the sclector magnets before the actuating' bar previously selected is removed from the aligned` slots ot the selector bars.
